15 The Google API Ruby Client makes it trivial to discover and access supported
20 Be sure `http://rubygems.org/` is in your gem sources.
22 For normal client usage, this is sufficient:
25 $ gem install google-api-client
31 require 'google/api_client'
32 require 'google/api_client/client_secrets'
34 # Initialize the client.
35 client = Google::APIClient.new(
36 :application_name => 'Example Ruby application',
37 :application_version => '1.0.0'
40 # Initialize Google+ API. Note this will make a request to the
41 # discovery service every time, so be sure to use serialization
42 # in your production code. Check the samples for more details.
43 plus = client.discovered_api('plus')
45 # Load client secrets from your client_secrets.json.
46 client_secrets = Google::APIClient::ClientSecrets.load
48 # Run installed application flow. Check the samples for a more
49 # complete example that saves the credentials between runs.
50 flow = Google::APIClient::InstalledAppFlow.new(
51 :client_id => client_secrets.client_id,
52 :client_secret => client_secrets.client_secret,
53 :scope => ['https://www.googleapis.com/auth/plus.me']
55 client.authorization = flow.authorize
58 result = client.execute(
59 :api_method => plus.activities.list,
60 :parameters => {'collection' => 'public', 'userId' => 'me'}
70 To take full advantage of the client, load API definitions prior to use. To load an API:
73 urlshortener = client.discovered_api('urlshortener')
76 Specific versions of the API can be loaded as well:
79 drive = client.discovered_api('drive', 'v2')
82 Locally cached discovery documents may be used as well. To load an API from a local file:
85 doc = File.read('my-api.json')
86 my_api = client.register_discovery_document('myapi', 'v1', doc)
91 Most interactions with Google APIs require users to authorize applications via OAuth 2.0. The client library uses [Signet](https://github.com/google/signet) to handle most aspects of authorization. For additional details about Google's OAuth support, see [Google Developers](https://developers.google.com/accounts/docs/OAuth2).
93 Credentials can be managed at the connection level, as shown, or supplied on a per-request basis when calling `execute`.
95 For server-to-server interactions, like those between a web application and Google Cloud Storage, Prediction, or BigQuery APIs, use service accounts.
98 key = Google::APIClient::KeyUtils.load_from_pkcs12('client.p12', 'notasecret')
99 client.authorization = Signet::OAuth2::Client.new(
100 :token_credential_uri => 'https://accounts.google.com/o/oauth2/token',
101 :audience => 'https://accounts.google.com/o/oauth2/token',
102 :scope => 'https://www.googleapis.com/auth/prediction',
103 :issuer => '123456-abcdef@developer.gserviceaccount.com',
105 client.authorization.fetch_access_token!
109 ### Batching Requests
111 Some Google APIs support batching requests into a single HTTP request. Use `Google::APIClient::BatchRequest`
112 to bundle multiple requests together.
117 client = Google::APIClient.new
118 urlshortener = client.discovered_api('urlshortner')
120 batch = Google::APIClient::BatchRequest.new do |result|
124 batch.add(:api_method => urlshortener.url.insert,
125 :body_object => { 'longUrl' => 'http://example.com/foo' })
126 batch.add(:api_method => urlshortener.url.insert,
127 :body_object => { 'longUrl' => 'http://example.com/bar' })
128 client.execute(batch)
131 Blocks for handling responses can be specified either at the batch level or when adding an individual API call. For example:
134 batch.add(:api_method=>urlshortener.url.insert, :body_object => { 'longUrl' => 'http://example.com/bar' }) do |result|
141 For APIs that support file uploads, use `Google::APIClient::UploadIO` to load the stream. Both multipart and resumable
142 uploads can be used. For example, to upload a file to Google Drive using multipart
145 drive = client.discovered_api('drive', 'v2')
147 media = Google::APIClient::UploadIO.new('mymovie.m4v', 'video/mp4')
149 'title' => 'My movie',
150 'description' => 'The best home movie ever made'
152 client.execute(:api_method => drive.files.insert,
153 :parameters => { 'uploadType' => 'multipart' },
154 :body_object => metadata,
158 To use resumable uploads, change the `uploadType` parameter to `resumable`. To check the status of the upload
159 and continue if necessary, check `result.resumable_upload`.
162 client.execute(:api_method => drive.files.insert,
163 :parameters => { 'uploadType' => 'resumable' },
164 :body_object => metadata,
166 upload = result.resumable_upload
170 client.execute(upload)
176 Included with the gem is a command line interface for working with Google APIs.
180 google-api oauth-2-login --client-id='...' --client-secret='...' --scope="https://www.googleapis.com/auth/plus.me"
182 # List the signed-in user's activities
183 google-api execute plus.activities.list --api=plus -- userId="me" collection="public"
185 # Start an interactive API session
187 >> plus = $client.discovered_api('plus')
188 >> $client.execute(plus.activities.list, {'userId' => 'me', 'collection' => 'public'})
189 => # returns a response from the API
